Raycast2D 360 Rotation

Hi Everyone,

I am trying to shoot a raycast from a gameobject which rotates but I am having issues creating the raycast end point. I have tried using COS and SIN but no luck. This is the effect I want to achieve:

This is the script I have written so far:

     // Raycast Start Point
     Vector2 StartPoint = AimStartPoint.position;

     // Raycast End Point
     Vector2 EndPoint = AimEndPoint.position; 

     // Create and Cast a Raycast Upwards
     RaycastHit2D Hit = Physics2D.Raycast(StartPoint, EndPoint);

     // Check if Ray Hit Something
     if (Hit)
     {
         Debug.Log(Hit.transform.name);
     }

     // Draw Raycast
     Debug.DrawLine(StartPoint, EndPoint, Color.red);

Could someone please share their ideas or tips how I can make this work without using a gameobject as an endpoint, I want the raycast to rotate around the scene and hit every gameobjects around it.
